Turpentine, in doses of twenty OF
thirty minims, will not only remove
headache, but produce, In a wonderful
manner, soothing influence.
A San Francisco concern is making
handsome pressed bricks out OF coal ashes
and cindeTs. These bricks have stood the
severest tests for strength, and are made
without baking or burning.
A new discovery is that by the use oil
citric acid or citrate OF silver sea-watey
may be made drinkable. By this mean
chloride of silver is precipitated and a
harmless mineral water is produced. An
ounce of citrate makes half pint of water
drinksble.
NJ. Peyrsud considers one OF the best
means of determining the death of an in
dividual to be cauterization by Vienna
/ paste. If the eschar sormI forms slowly
and is Of a yellow color or transparent,
! death may be positively declared while if
1t be red, brown or black life still exists.
Mildsw spots may be removed by a mix
! ture Of soft soap, boiled starch, salt and
!, lemon juice. Apply to the spots aud
bleach in the sun four hours If the spots
be old enough TO resist this treatment rub
then apply thick starch made with cold
water and hang out in the sun.
An interesting series of experiments has
been made by DR.. J. W. Fraser on the in.
huence of our common beverages on d.
gestion. Among these drinks he finds
that water Is usually the best 0iinfusions,
tea or cocoa acts most faverably when
bread is eaten, and coffee is the best for
use with meat or eggs Eggs are the best
animal food with infused beverages, and
should be soft boiled when tea is the bevsr-
age and hard boiled with coffee or cocoa.
EngraviDgs may be transferred on white
paper as follows: Place the engraving a
few seconds over the vapor of iodine. Dip
slip of white paper in weak solution of
starch, and when dry in a weak solution of
oil of vitrol. When again dry lay a slip
upon the engraving and place both for
few minutes under press. The engraving
will be reproduced in all its delicacy and
finish. Autographs and printed matter
can not be so transferred with equal sue
cess.
DR.. c. c. Stockard, of Columbus, Miss,
referring to communication of Dr.. Boyd
concerning the insolubility of gelatIne
capsules.i writes that he has frequently
seen gelatine-coated quinine pills pass
from the bowels updigested, even where
there was no gastric inflammation. He
has never known this to occur with freshly
filled gelatiHe capsules, nor with gelatine.
coated pills, except those OF quinine. Tue
latter he regards as so unreliable that he
never prescribes them.
Gold heaters, by hammering can reduce
gold so thin that 2S2, 900 must be laid upon
each other to produce the thickness of an
inch; yet each leaf is so perfect and free
from holes that one of them, laid on any
surface, as in gliding gives the appearance
Of solid gold. They are so thin that, If
formed into book, 1 200 would only oc-
cupy the space Of a single leaf of common
paper; and an octave volume of an inch
thick would have as MANY pages as the
books OF a well stocked library of 500
volumes, with 400 pages in each.
According to psper read by Me-. John
MGray, before the Royal Society OF L iiu-
burg, ., 243 cubic miles OF rain fall annu-
ally on areas with inland drainage.
Such areas extend to Ii, 486. $50 square
miles. The land draining directly to the
ocean has an area OF A 2l1 900 square
miles, of which 80 S29. $50 square miles
have ten inches or more of rainfall. The
mean discharge from this area into the
ocean is $3.50 cubic miles annually The
total weight OF substances carried by this
means to the ocean, is more than $780,
600, goo tons each year.
Wood oil is made on a large scale in
Sweden from the refuse of timber cuttings
and forest clearings, and from stumps and
roots; and, although it cannot we'll be
burned in common lamps on account of
the heavy proportion of carbon it contains,
it furnishes a satisfactory heht in lamps
especially made for it, and in it's natural
state is said to be the cheaper of illumin-
atipg oils. Thirty factories produce about
thirty thousand liters of the OIL daily;
turpentine, creosote, acetic acid, charcoal,
coal tar oils, and other useful substances

At recent meeting of the Medical So
ciety of Berlin, DR.. Lewis made a COM
munication on the physiological effects of
restnous extract prepared from kava
Piper methiSticBml Ito which he attributes
local action similar to that of cocaine.
When placed on the tongue il produces a
sensation of heat, which is soon followed
by anesthesia. Applied to the eye it at
first causes smarting, with an abundant
flow of tears; this is followed by complete
and lasting anesthesia Of the cornea and
conjunctiva. Subcutsneous injections
produced insensibiiity of the neigh boring
tissues without setting up inflammation.
In the construction Of flint walls, accord
ing to Mr.. Fowler's description in the Ar
chitect, a formation is made between two
planks, or ,rames, the lime being poured
among the fints in LIQUID state; in some
cases the largest hints are selected, two
courses laid with them-one outside, the
other inside OF the wall-and the center
filed up with smaller hints and liquid
mortar, the lime to be mixed with sharp
sand and clear gravel. The corners are
formed of brick, and longitudinal bands Of
brick are also introduced, from two feet to
two feet six inches apart, these bands be-
ing formed to two courses of brick, one
header and the other stretcher, or, where
bricks cannot be had, fat-bedded stones
may be used for these bands.
